DZ — Algeria

Algeria is the largest country in Africa by land area, spanning over 2.38 million square kilometers across the Sahara Desert and the Mediterranean coast. Located in North Africa, it shares borders with seven countries including Morocco, Tunisia, Libya, Niger, Mali, Mauritania, and Western Sahara. The country gained independence from France in 1962 after a prolonged war of independence. Algeria's economy is heavily dependent on hydrocarbons, making it one of Africa's largest oil and natural gas producers. For developers, the DZ country code appears in locale strings like ar-DZ for Algerian Arabic, which uses distinct number formatting and date conventions. The .dz top-level domain is administered locally, and the +213 dialing code is essential for phone number validation in North African telecommunications systems. Algeria's diverse linguistic landscape — Arabic, Berber, and French — makes it an important test case for multilingual i18n implementations.
